Track and share your activity. Measure your workouts. Monitor your health. And stay connected to the people and information you care about most. Now you can do it all even faster than before, thanks to a powerful processor.

With its powerful processor, Apple Watch Series 1 is ready to go when you are. Your favorite apps launch immediately and are always up to date, so you can perform everyday tasks - like viewing your Activity rings, checking your calendar, or replying to a message - in an instant.

Your stand, move, and exercise rings show you how active you are every day and inspire you to move a little more. See if you've been sitting too much. Track how many steps you've taken and how many calories you've burned. And aim for 30 minutes of exercise, even if it's not all at once.

Choose from a variety of indoor and outdoor workouts - including biking, running, and elliptical - then set your goals and get moving. However you work out, Apple Watch Series 1 accurately measures your movement. Select up to five metrics to view at once and even mark segments.
